KYIV, Ukraine (AP) — Russia fired hundreds of drones and dozens of missiles at Ukraine's biggest cities in an overnight barrage that killed at least 11 people and set fire to a world-renowned religious landmark, Ukrainian President Volodymyr Zelenskyy and other officials said Monday.

The attacks on the capital of Kyiv, and the second-largest city of Kharkiv, came after Zelenskyy and Russian President Vladimir Putin spoke separately by phone with U.S. President Donald Trump on Sunday. The exchange suggests Washington hasn't given up on its diplomatic efforts to stop the fighting that followed Moscow's all-out invasion of its neighbor in February 2022.

The war in Ukraine is also set to feature in talks Tuesday by G7 leaders at a summit in France. Zelenskyy and Trump are due to attend, with the Ukrainian leader pushing his country's plight while the Iran war diverts international attention.

"This is how Russia shows the world its intention to continue the war," Zelenskyy said in a post on X, referring to the overnight attack on civilian sites that included the Kyiv-Pechersk Lavra, an 11th-century monastery complex.
